Abstract

The utility model discloses a vacuum drainage system of washrooms in underground buildings. The drainage system includes a vacuum pumping station system which is connected with a feces system by a blow-down main pipe; the blow-down main pipe is connected with at least one hold-up tank by a pipeline; and the hold-up tank is connected with a washing system and a urine system. The vacuum pumping station system generates vacuum in the blow-down main pipe, under the pumping action of the vacuum, sewage and waste water produced in the toilet is pumped into the blow-down main pipe, and then transferred through the blow-down main pipe to the vacuum pumping station system, where the water is pressurized and promoted to a ground municipal sewage pipe network. The vacuum drainage system of washrooms has the advantages that the pipeline is flexibly arranged and capable of elevations; the toilet flushing needs small water consumption; the system is highly airproof to avoid smell leakage, thereby realizing a more humanizing toileting environment; and the utility model provides a novel drainage system of washrooms with good hygiene, environmental protection and flexible system arrangement.

Description

Washroom, underground building low-pressure drainage system
Technical field
The utility model relates to a kind of low-pressure drainage system, washroom, particularly a kind of underground building low-pressure drainage system.
Background technology
The underground building toilet drainage mostly uses the gravity drainage technology at present, be that sewage, the waste water that produces in the washroom flows in the interior temporary sewage reservoir of pump house by the gravity blowoff line earlier, when the sewage in the sewage reservoir, waste water reach a constant volume, the dredge pump that is arranged in the pump house is started working, and the dirt in the sewage reservoir, waste water are promoted and is drained in the municipal blowdown pipe network on ground.Because be to adopt gravity drainage, the shortcoming one of this drainage system is when the laying of blowoff line, must have certain gradient, and sewage reservoir must be arranged in the space of washroom subterranean layer, can not realize co-layer draining; The 2nd, the sewage reservoir floor space is big, and the sealing difficulty causes the interior stink of pump house big; The 3rd, gravity drainage only depends on water to wash lavatory pan, and it is big that all wash water consumption at every turn, even the each water consumption of water-saving lavatory pan also will reach about 6L, is unfavorable for the saving of water resource.
Summary of the invention
The utility model is at the deficiency that the gravity drainage system technology exists between building hygiene under the terrain, and a kind of washroom, underground building low-pressure drainage system with advantage such as simple in structure, easy to use is provided.
For achieving the above object, the utility model adopts following technical solution:
Washroom, a kind of underground building low-pressure drainage system, it comprises the Vacuum Pumps Station system, this system is connected with the stool system by the blowdown main, and the main of blowdown simultaneously also is connected with at least one holding tank by pipeline, and holding tank then is connected with the urine system with the system of washing one's face and rinsing one's mouth.
Described Vacuum Pumps Station system comprises the vacuum unit that is installed in the pump house, and the vacuum unit adopts volume type rotor pump; The unit inlet is connected with the blowdown main, and the unit outlet links to each other with the municipal wastewater pipe network by lift line.
Described big defecation system comprises at least one in pan or the water closet, and they are connected with the blowdown main by the pipeline that has bleed valve respectively.
The described system of washing one's face and rinsing one's mouth comprises at least one in washbasin or the mop pool.
Described urine system comprises at least one urinal.
Described holding tank is provided with bleed valve.
The utility model is provided with a cover Vacuum Pumps Station in pump house, the pumping plant inlet is connected to the washroom by the blowdown main, and the pumping plant outlet links to each other with the municipal wastewater pipe network by lift line; The Vacuum Pumps Station main frame adopts volume type rotor pump, this kind pump has the function of suction one, during this pump work, on the one hand can in the blowdown main of the inlet of pump, produce vacuum, promote the municipal wastewater pipe network that enters ground by the pumping plant outlet after directly pressurizeing dirt, the waste water of coming from the entrance pipe suction simultaneously on the other hand, its effect is equivalent to vacuum pump and dredge pump is worked simultaneously.Lavatory pan in the washroom (pan and water closet) is connected to the blowdown main by blow down branch, bleed valve is housed on the blow down branch, during toilet stool washing, bleed valve is opened, vacuum in bedpan and the blowdown main is connected, flushing water begins to wash bedpan simultaneously, sewage in the bedpan enters the blowdown main under the acting in conjunction of the suction force of vacuum and water flushing ability, and be transported to Vacuum Pumps Station by the blowdown main, obtain pressurization in Vacuum Pumps Station, be raised in the municipal wastewater pipe network that is drained into ground.
Urinal, washbasin, the dirt that mop pool etc. produce, waste water, utilize the effect of gravity to collect in the middle holding tank earlier, holding tank is connected to the blowdown main by blow down branch, bleed valve is housed on the holding tank, when the liquid level in the holding tank reaches certain level, bleed valve is opened automatically, the interior vacuum of holding tank and blowdown main is connected, dirt in the holding tank, water wasting enters the blowdown main under the suction force effect of vacuum, and be transported to Vacuum Pumps Station by the blowdown main, obtain pressurization in Vacuum Pumps Station, be raised in the municipal wastewater pipe network that is drained into ground.
The beneficial effects of the utility model:
It adopts the vacuum type drainage principle, and whole system is a closed system, does not have any evaporating, emitting, dripping or leaking of liquid or gas, so air ambient is good in washroom and the pump house, no stink makes the environment hommization more that goes to toilet.
In the flushing process of lavatory pan, adopt vacuum draw sewage simultaneously, reaching under the situation of equal developing result, saved wash water greatly, according to statistics, the lavatory pan wash water is saved more than 2/3.
The vacuum type transmission is adopted in transmission in pipeline, so pipeline laying needn't be considered the gradient, can freedom detour up and down as pressure pipeline, can realize co-layer draining easily, and the transmittability of high speed has determined little many of pipe diameter force of gravity system pipeline.
The utility model does not need to be provided with sewage reservoir again, has saved the area of pump house greatly and has improved the interior working environment of pump house.
